Low Price Stainless Steel Bearing Bushings
Stainless Steel bearings compared with ordinary bearings, not onlt material has obvious
advantages, but also in the process, the accuracy of the control, more than ordinary bearings to
be more stringent. In the course of work stainless steel bearings work stable, low noise,
corrosion-resistance, widely used.
Bearing rings and rolling materials used AISI SUS440C stainless steel ( domeatic grade:
9Cr18Mo, 9Cr18 ) by vacuum quenching and tempering treatment, cage and sealing frame material
using AISI304 stainless steel ( domestic grade: 0Cr18Ni9 ). Stainless steel bearings compared with ordinary bearing steel, there is a stronger anti-rust, anti-corrosion, select the appropriate
lubricant, dust over, etc, can be -60 ℃~300 ℃ environment. Stainless steel deep groove ball
bearings can withstand moisture and a number of other media caused by corrosion. This type of
single-role deep groove ball bearings and carbon chromium ( rolling bearing ) steel manufacturing
standard deep groove ball bearings, with a deep bearing raceway groove, bearing raceway and the
ball between the high degree of cooperation. Stainless steel bearings because of high mechanical
strength, load capacity, widely used in food processing, medical equipment, pharmaceutical
The main purpose:
Medical equipment, low temperature engineering, optical instruments, high-speed machine
tools, high speed motors, printing machinery, food processing machinery.
1.Excellent corrosion resistance: stainless steel bearings are not easy to rust, with a
strong corrosion resistance.
2.Can be washed: stainless steel bearings can be washed down without having to re-lubricating
oil to prevent rusting punishment.
3.Can run in the liquid: due to the material used, we can run the bearings and bearings in
4.The slow drying rate: AISI316 stainless steel, do not need oil or grease anti-corrosion
protection. Therefore, if the speed and load are low, there is no need for lubrication.
5.Health: Stainless steel natural clean, no corrosion.
6.High heat resistance: Stainless steel bearings are equipped with high temperature polymer
cage or not in a complete complement structure of the cage, can run at a higher temperature range
of 180 °F to 1000 °F.( Need to match high temperature grease )
Reason for stainless steel bearing failure:
Stainless steel bearing fracture failure is mainly due to defects and overload two factors.
When the external load exceeds the material strength limit caused by part fracture known as
overload fracture. The cause of the overload is that the host is faulty or improperly installed.
Bearing parts f the micro-cracks, shrinkage, bubbles, large foreign debris, overheating tissue
and local burns and other defects in the impact of overload or severe vibration will also cause
damage in the defect, known as defective fracture. It should be noted that the bearing in the
manufacturing process, the raw materials into the factory re-inspection, forging and heat
treatment quality control, processing process control can be correctly analyzed by the instrument
whether the exsistence of defects in the future must still strength control. But in general, the
failure of the stainless steel bearings usually occurs mostly for overload failure.
